This high school reunion snapshot was written by Weezer frontman Rivers Cuomo with the album's co-producer Butch Walker. Rhythm guitarist Brian Bell told MTV News that both Walker and the album's other co-producer, Garrett "Jacknife" Lee had powerful, positive and very different impacts on the album's sound. He explained: "I could see us continuing to work with Butch in the future... he brought it back around to Weezer rock music and us playing together as a band."
Cuomo described this to Billboard magazine as a "kind of a witty, party jam."
Butch Walker lives just down the street from Cuomo in Los Angeles. "I walked over to his house and we started talking about high school reunions," Walker recalled to Billboard magazine. "We looped the idea back and forth on the guitar for a few hours and came up with 'The Girl Got Hot.'"
